2020 Yamaha yz250fx stalling test
250FX is such an underrated bike.
great package for sure
It's very very under rated, everyone is KTM 300 CRAZY... I do admit the 300 is crazy good. The fx is more stable, comparing them back to back stock. Fx is cheaper.
I wish Yamaha would make a 350fx with a longer stroke for better bottom end torque.
I’m right with ya! I’m waiting for a 300 or 350 FX I would by one before they even hit the floor!
They will stall easier
@@mathews0618 No. Not a long stroke 350. I have a Beta 390 and it almost *never* flames out.
The key to stall prevention is compression ratio. Keep it low and it wont stall. They should make a power compression ratio valve lol. Silly
@@mathews0618 actually, the key to stall prevention is good clutch skills. But yes low compression too.
Very interesting ! I found a few (very few) comments on the topic in forums. But this 'no shifting' test going up a hill is a very smart . I'm looking at getting one. Thanks!
Cool man, glad you like it👍
Great video man. I’m genuinely impressed. It was super low in the rpm several times and kept going. I had a crf450x that flamed out constantly. I switched to a xcw tpi. That Yamaha did well. I imagine a WR would be even better. I’d watch that video
thanks Adam, glad you liked the test. Yes, it was quite impressive at some places the rpm went really low and kept pulling up.
@@dirtniron Hay thanks for the great review. How do you think it compares to the 2019 ktm 350xcf?
Those are exactly the kind of trails I rode for over 40 years and that is the bike I could have used......a lot of times when you're really excited about getting up the trail, you get a little sloppy and don't get your shifts quite right. When you have a bike that will lug without stalling out, it makes your day so much more fun and allows a fella to get away with less than perfect riding skills every minute. When you're done with that bike send it my way! It might make an old guy look a bit younger again!! Hang in there, Rado! Thanks for the look back down the trail; it sure gives a feel of how steep/technical it was.....good job. Keep the Faith, Tom P.S. A fella would like a 300 for that kind of hills, maybe........or it may "feel" heavier(even if it wasn't) due to bigger piston swinging around. It is almost impossible to get the bike too light when you're an old geezer like me.
yes Tom, little bigger displacement would be good. I have 270 kit on the bike right now and it feels great! I think you would love it!
@@dirtniron 270 is about all you want to punch it out to because any more and your bore/stroke ratio start doing weird things to your powerband and vibration. Sure looks about right to me. You did a super job of pushing it to the limits in terms of how much lugging it would take without flame-out. I hear a lot of guys complaining about notchy shifting on the Yamahas......I dunno, I've own/ridden a lot of Yams and I've not been bothered by the shifting.......what are you finding from that standpoint? I'd like to hear your experiences. Most of where I rode was about like what you rode in this upload with more loose rock. I'd rather ride rock than mud any day! I hate mud. Keep the Faith, you'res my main man!
@@tomnekuda3818 I did not find anything weird about Yamaha shifting, feels pretty much the same as any other bikes.. I guess I am not so sensitive to these little things.. glad you liked the test Tom, appreciate it! stay safe ;)
Rado...you have amazing content...I like that you mention what gear you are in...when you shift...clutch or no-clutch...really gives us a good perspective into what the bikes can do. Thanks!
I appreciate that Greg! Glad you find the content helpful
I own a 2019 300rr Beta and 2020 yz250fx.....for the slow stuff, the Beta is the far more competent bike for sure, awesome bike....but the bike that makes me super excited to ride is my yz250fx, what a blast it is, the engine's power curve, the sound, the suspension....the riding experience is just the best with this bike especially in the medium to quick stuff.....not a bike for hard enduro or the very slow stuff, engine has too much compression and too reactive of a bike to ride in those conditions but for everything else, its unmatched!
Thanks a lot for sharing! I agree 100% this bike feels amazing once you go little faster, so much fun!
Thats why i sold my FX. It was too aggressive, for me mainly exploring. Riding wide open, it was exciting.
IDK man, my 19 250fx is great on the slow stuff, I did put a throttle tamer on it and went from 50-52 on rear sprocket, I very rarely stall it, couple times this past weekend but I was so tired at end of the day
I find that my YZ250fx will lug very well. Where it has issues is if I chop the throttle and then get back on the gas quickly, like when I need to lift the front end for a log. That’s when it stalls or flames out unexpectedly.
thanks for sharing
Can the Tuner App help in that matter? I'm asking because I'dd like to do slow technical stuff on a 4 stroke (what I have is heavy and tiring). And I don't want the reliability issues of the European bikes. So FX is an option.
I believe these 250fxs are the best lugging 4 stroke
great bikes for sure!
Good review. But the comments are respectful and I appreciate that. Rare to see mature comments.
I appreciate that, thanks
Thanks mate. Good honest and real unbiased content we can trust👍👍
thanks mate, glad you see it that way! appreciate it
With the 2020 YZ250FX there is also a Tech Bulletin number M2020-006 this is related to starting issues, stalling, and hard starting when Hot. The dealer will re-flash the ECU with new parameters that the "App" doesn't have access to. This is a good one to have done.
yes, thats right! thanks for sharing
I don’t have that bike but looks like it will do trail and track very will watching this channel thank you for this video it was very informative 👍
glad you like it, thank man!
I have a 19 250fx, never stalls with proper clutch use, I was extremely tired today after doing around 27 mean of tight single track and stalled it a couple times but it was me not the bike, I lug around in second gear most of the time on these trails and it does not stall, greatest bike in my opinion, wouldn't have anything else
thanks for sharing Terry!
Awesome video! I love how you explain what gear you are in AND if you are clutching or not. What MAP were you running? Wild or mild?
Great video Rado! That YZ250FX seems like a great bike. Beautiful terrain out there, I would love to ride it one day. JJ
thanks bro, I can show you around if you ever come to ride here
@@dirtniron would love to some day Rado! Thank you!
Yeah I can vouch for Rado! That section is very steep, technical, and Rocky! Haven't been up there in a year or so. Time to go back. Great video! I'm going to have my first opportunity to ride that exact same bike this weekend. Can't wait!
thanks Todd, have fun this weekend!
I've had my 20 250fx since august and its yet to stall on me. If I know I'm going to be doing some slow, tight crawling sections I just flip into mild power mode and for me it seems to be able to handle very slow speeds without stalling. Super impressed with this bike, I love it.
great bike for sure, thanks for sharing!
Those yz250 are sweet bikes 💪
I think so too!
Interesting ! I have a 2020 KLX 300R, and I gotta say...I'm just about ready to upgrade. Don't get me wrong, it's been great...taught me how to ride but, I want something a little more powerful, quicker, and ultimately something LIGHTER. Good lord the KLX300R is like 280 pounds.. I'm over it. Been looking at this 250FX and the KTM 350 XCF.
Right on! both bikes will be great. pick the color :)
I'm used to a 250 4 stroke(283cc with the big bore kit).. We have very little "fast terrain" but I still get the bike around pretty good. It is a little unpredictable though, at times I can't believe how well the engine lugs and then there's those moments when it'll flame out and I almost have know idea why 😐
thanks for sharing brother!
Great video fantastic bike stay safe looking forward to next one 🇬🇧👍🏻
Thanks, will do!
Apparently, you can tune stalling out further with GYTR tuner by adding ignition and removing fuel at low RPM. Or something like that.
I am sure you can play with it on your phone app
I have a 2019 yz450fx and read alot of things about it flaming out or not wanting to start in gear wich I have had no problems with whatsoever.
Starts in gear almost everytime flawlessly and basically never flames out so I'm not sure what people were talking about
thanks for sharing Jake
I just out a Rekluse Radius CX in my bikes and dont have to worry about it.
thats one option
Rekluse clutches are cheating in my opinion, learn to use a clutch
@@terrywilson1362 Is it cheating to re-map? Re-tune suspension? Put in lowering links? Add hand guards? Custom exhaust? Etc. WTF @Terry Wilson?
@@georgebanker2669 all that stuff is not learning to use it, hand guards are for safety, suspension is just so you can ride the bike, learn to use a clutch, it makes you a better rider, and I said it's just my opinion and I'm entitled to it
@@terrywilson1362 Agree, that we are all entitled to our opinions. Glad we can discuss this civilly unlike some of the recent differences of opinion that are making headlines.
I’ve seen some movies here on UA-cam about stalling 4-strokes. I think these people just don’t have no feeling when to shift down, how to use the clutch and the gas. If you ride like a moron of course it stalls.
Exactly. The same whiners who say 4 strokes stall too much are the ones needing to slip the clutch to stay on the pipe of their smoker.
yes clutch control is important, but some bikes stall more than other bikes.. this one wasnt bad at all
Clutch control isn’t just for 2t’s. I manage to lug my 2017 FX some rocky rough single track in the PNW. Sure sometimes I stall it but there’s plenty of power to crawl up. If I had $ like DBC dude to buy a new bike every 6 months I would. Love my FX even after 105 hours.
Good video! I'm testing a 2020 yzf250 for the woods on my UA-cam channel. I'm cheating a little bit by putting a recluse radius cx clutch in mine. Zero stalling!
yea, rekluse is a big cheating tho ;)
I have the same bike..... I HATE it for slower stuff. The suspension is WAY to stiff
My bike has revalved suspension for woods riding. It is awesome.
The same people that whine about 4 strokes stalling have to clutch their smoker to stay on the pipe. Its simple riding technique, applied differently to different engines. And FFS rev out a lower gear in a technical situation instead of trying to clutch a gear high.
yea, good clutch control is important on 2 and a 4 stroke
@@dirtniron Ha sorry wasnt referring to you in the vid! I love that u tested this out. Proves a lot of Keyboard Riders wrong. I rode a '15 FX where u do for years, then switched to a CRF450X for the desert but did a lot of single track by McCain on it and loved both bikes. I got tired of recent issues in CA and moved back to WI and probably swapping to a wr250r for the logging roads. Iv had a ton of bikes, but nothing like the 250FX motor
I have the 450fx and what I use in the rocks and I believe the 250fx has the same tunes available with the app is mx feeling power in map 1 and map 2 is the mild tune and that map is perfect for rocks and tech stuff. You can actually lug it a little more on that tune and its much easier to ride through those areas so try it and see how it is.
thanks for sharing Nate!
@@dirtniron your welcome.
I have this bike, did you get the bulletin done for the running rich condition? It is free and really helps the bike out. Only issue I have with this bike is the suspension is way way to stiff for slower stuff and rocky trails. It tosses you around like a rag doll
yes, its better for faster stuff and feels great on MX track as well. I did big bore and have custom map - runs good now
For primarily woods riding on the east coast, would you choose 250fx or WR450 (uncorked)? I've read the 450fx can still be a bit of a handful even with a mellow map. 205lb rider (probably 215/220 with full gear), 50 years old in good shape.
I had both bikes 2020 250fx and 2019 wr450 uncorked.. both are super fun, probably would go with 250 for tighter woods riding. Check out @dirtbiking with donnie youtube channel, he has 205fx and does a lot of woods racing. good luck!
@@dirtniron Thanks for the reply! I already watch Donnie's channel. Asked him about comparing to a 450 but he's never ridden one. I suspect the 250 would be the ticket for me.
Great channel. I really like your reviews.
right on, thanks brother!
I don't know why but I have always stalled more on 2 strokes than 4 strokes. I don't know if that's because I can hear that point before stalling better with the four stroke and I just naturally use thee clutch.
interesting, thanks for sharing!
The sweet spot would be if they made a 350 or 400.
yes, 350 would be very interesting!
Which map was the test done with.(I own one of these.)
mx map and I also got a custom one from Twisted
Were did you shoot this video ?
Socal - San Bernardino Forest
Wow nice bike! Hey where is that trail?
its by Hemet in San Bernardino forest
Really, I live in riverside in I ride in hemet and San Jacinto but idk what trails is that, do you know the name, or where is located at?
Does the yz250fx compare to the wr250f?
wr is choked up, once you open it up its similar but there are still some differences
are these bikes lightweight?
The 250fx is 245 pounds.
My 450fx is 256 wich on paper is a bit heavy but doesn't feel heavy at all out on the trails.
You cant always go by the weight on paper
not the lightest on the market but feel pretty good
Im gonna get a full size bike soon from my kx100 and saw some yz250fs and im about 5ft 8. do you think i could ride one ?
@@randomvideos5356 yea I think you will get used to it. Would have to touch the ground with only one foot at a time but its doable for sure
How does it compare to the honda 250rx?
similar but the gearbox makes more sense on FX for trail riding
@@dirtniron is engine braking and vibration similar also on both bikes?
Did you remove the 270 kit? Or did you shoot this prior?
I shoot this video prior to 270 kit, with the kit its even better. I wanted to have a video showing how the bike behaves 100% stock out of the box.
@@dirtniron Sweet! I picked up a 250FX in april. Just had it reflashed and suspension revalved and sprung for me. Bike is amazing!
what are the changes after the reflash? where do you feel it? Mine works great with 270 kit, I did not do the reflash, just played with the maps.
@@dirtniron I had read about the hot start issues with 2020s before I bought it. I asked my dealer to check on it for me before I took the bike, but they said its fine. So I put a few hours on it, but it gradually started flaming out more and more each ride, usually with clutch all the way in too. Then would not restart. Finally I fried my battery trying to restart it. Took it to another dealer for the reflash and it is perfect now.
@@dirtniron Oh and I also run the Smooth Linear Map because I ride tighter woods trails.
I had to get my 2020 reflashed cause it would stall so easy. It would stall all the time. Yamaha has a bullentin on it. Beside that bike is freaking amazing. Just aggregating on how easy it was stalling but reflashed fixed that issue
I heard about it, it should also help with starting.. I put 270 kit on mine and its all good, no complains about starting now
What did you ask the dlr to do precisely? Is it the CO change that ive read about?
Same as wr 250f ?
Different tranny, little different engine but very similar once you uncork wr
@@dirtniron in my country är 250f is a pure race bike . No one use fx models
